Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 2015
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Likely exempt from AB 1482. Housing with a certificate of occupancy issued within the previous 15 years is exempt from the state rent cap and just-cause rules.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The 350 Linden Street property is a 4-story, 7-unit mixed-use building constructed in 2015, located in Hayes Valley and currently owned by Golden Properties LLC. The building's construction and safety systems development spanned several years, beginning with a substantial $1.55 million project filed in 2007 and including significant milestones in 2013 such as excavation work ($50,000), installation of a new fire sprinkler and standpipe system ($86,500), and a comprehensive fire alarm system installation ($12,800) in 2014. Throughout the construction period, multiple street space permits were issued between 2013 and 2014, each costing $1.

In late 2014, the building experienced significant compliance issues when a complaint was filed alleging deviations from approved plans regarding property lines, windows, building frontage, egress windows, handicap accessibility, and notably an oversized roof deck that was not installed according to manufacturer's instructions. This led to multiple Notices of Violation (NOVs) issued in October and December 2014, with associated monthly monitoring violation fees of $52. The abatement process was completed successfully in October 2015, resolving these compliance issues. Since then, there have been no recorded complaints, violations, or permit activity, suggesting the building has been stable and maintained compliance with regulatory requirements since the resolution of the 2014-2015 issues.

Risk rating

How 350 Linden St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
62ndpercentile

Out of 1027 buildings in this neighborhood, 390 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

DBI complaints, owner's portfolio

Complaints across all of this owner's buildings over 7 years.
